This required adding a few headers that were found transitively before, but not too many. This is sadly a fairly manual process of opening every file in my IDE, but I think I got everything in `//common` and `//toolchain`. There are a few cases where technically we don't need `foo.h` to be included into `foo.cpp`, but I've forced those to stay with a pragma. I've tried to catch the places where we can cut deps in Bazel as well, but not sure I got all of those. I had been noticing these in other PRs and it seemed better to isolate the change.
